Giesemann Announces Bluetooth Interface for Teszla LED Fixtures

Giesemann BT-Interface

When it comes to good looking and well designed aquarium lighting products, there are few out there that rival the Giesemann Teszla LED fixtures. Besides their stunning design, the lights are also loaded to the brim with features, and it looks like they’ll be getting a key accessory to make their use so much easier. Announced at MACNA, Giesemann is releasing a Bluetooth interface, simply called the BT-Interface, that allows users to control up to four Teszla or Teszla-XT LED fixtures with their PC, Mac, smartphone or tablet. With the software interface, aquarists can fully adjust all three color channels using the multi-point time and intensity plot system, create elaborate storm and cloud simulations, and enact a 28-day real-time lunar cycle.

The BT-Interface does require a physical connection to each of the fixtures that it controls. This is done through any of one of four on-board USB sockets and their associated cables, but once connected, the lights can be controlled via Bluetooth connection with any capable device. The LEDs in the Teszla lights are controlled by microprocessors, which receive their operating instructions from the interface system.

The BT-Interface has a European price tag of € 199.00, and we haven’t seen an official price for the US Market. The software, on the other hand, is available free of charge.

Giesemann’s use of Bluetooth instead of WiFi has both its ups and downs. The big downside is the limited range of Bluetooth. With a WiFi capable device, you could control a light from virtually anywhere in the world. With Bluetooth, on the other hand, you pretty much have to be in the same room in order to make changes. Now, one could easily make the argument that you don’t want to adjust the color of the light from a significant distance, such as when you’re traveling, but we are not fans of being handcuffed by technology. The other downside is that the fixtures require a constant connection to the interface, instead of receiving their signals wirelessly. This is not a problem caused by the interface itself, but a limitation of the light fixture. Wires can be very unsightly, especially for a fixture who prides itself on clean lines and a sleek look, and we’ve all seen how popular devices like the ReefLink from EcoTech Marine are and how users have basically demanded the wireless communications.

All that said, the Teszla has been around since just before the announcement of the revolutionary Radion, and up until just recently, the Radion didn’t even have full wireless control (technically it’s still not available to the masses, but it’s virtually here already). The point we’re trying to make is that a new Teszla model might have WiFi and other wireless options, , with the BT-Interface possibly acting as a bridge to get to that point. Of course, this is all just speculation on our end, and regardless of wireless features, it’s still an amazing looking fixture.

  • “but we are not fans of being handcuffed by technology.” well said. Numerous LED fixtures on the market provide the proper light to grow corals, provide eye pleasing illumination of the tank, and the fixtures look cool.(the last one being a moot point for me, but many aquarist demand it) At this point we are all craving control. USB cords should never be mentioned any more with equipment like this and blue tooth is just a tiny babe step in the right direction that really falls short. Even just having WiFi is using technology built many years ago and soon about to be old news. Neptune Systems is moving in the right direction by offering a cloud based option. The best option is to have WiFi, wired Ethernet, and cloud based for the end use to choose from.

    Sorry, but how is wifi going to be old news? New wifi standards are being released all the time. 802.11n is still being adopted and 802.11ac hasn’t even started to be adopted except by uber geeks. What technology is going to be used to connect wireless device to the webbernets f wifi goes away? You’re still going to need a way to connect to some random cloud service. Are you suggesting LTE or some other cellular data technology? Personally, is rather have services running on my LAN and not in the cloud. You’re putting a lot of faith in a random company in regards to security when running stuff like this in the cloud. I really don’t want a cloud service getting compromised and some random person running off my return pump or blasting my LEDs at 100% and bleaching my corals. Just food for thought.

    • Note I said, “The best option is to have WiFi, wired Ethernet, and cloud based for the end use to choose from.” I said this specifically for this exact reason. Some people, tech heads mostly, will worry about security, but the vast majority could care less. Just look at banks. Having access to bank accounts from any mobile phone from anywhere in the world is a huge security risk, but people want that. If you are the only bank with out a mobile app then you may lose a lot of customers specifically for this reason. Same may happen when it comes to reef keeping and aquarium control. If say only two controllers exist and one requires you to use DNS, email configuration, port forwarding….. and the other has the option of either the complicated setup or “plug and play”. Keep in mind Neptune became immensely more popular not because they released the Apex, but the Apex Jr. People first look for price and ease of use and then later crave power. Many didn’t even consider Neptune in the past as it was complicated and expensive.
